Abstract
A fuel-isolation system includes a valve body that defines a flow passage that extends from an inlet to an outlet, a rupture diaphragm in the flow passage and fluidly sealing the inlet from the outlet, and an actuator situated adjacent the rupture diaphragm. The rupture diaphragm is integral with the valve body. The actuator includes a plunger that is configured to move and cause breach of the rupture diaphragm and thereby fluidly connect the inlet and the inlet.
Claims18
A fuel-isolation system, comprising:
- a valve body defining a flow passage extending from an inlet to an outlet, and in addition to the inlet and the outlet, the valve body defining a test port that opens into the flow passage and is fluidly connected with the outlet but not the inlet;
- a rupture diaphragm integral to the valve body, the rupture diaphragm in the flow passage and fluidly sealing the inlet from the outlet;
- an actuator situated adjacent the rupture diaphragm, the actuator including a plunger that is configured to move and cause breach of the rupture diaphragm and thereby fluidly connect the inlet and the outlet;
- and
- a propellant tank having an outlet attached to or integral to the inlet of the valve body.
